I like my neighbour and

Once upon a time in Millennial age, there are two online friends who have known each other on Twitter, haven’t done any face reveal over years or anything like that, not joining any selcaday whatsoever, just so they can surprise each other once they get to go to the Jonas Brothers’ concert. They talk about anything and everything, until one day, this one friend named Donghyun started to share stories of his loud neighbour, who keeps changing bed sheets. Donghyun is sure that this particular neighbour is just as clean freak as he is, but Joochan tries to convince Donghyun otherwise.
